High Performance with Lower Fuel Consumption

  • Use up to 20% less fuel than the 320F excavators.
  • Match the excavator to the job using power modes including new Smart Mode that automatically matches engine and hydraulic power to digging conditions.
  • The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.
  • Your joystick commands adjust pump flow based on valve priority putting hydraulic pressure and flow where it needs to go giving you improved fast light-to-medium load cycle times.
  • The electronically controlled, turbocharged engine meets U.S. EPA Tier 4 Final and EU Stage IV emissions standards using a transparent aftertreatment system that requires no operator input or downtime.
  • Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
  • Don't let the temperature stop you from working. The excavator has a standard high-ambient temperature capability of 125 º F (52º C) and cold start capability of 0º F (-18º C). An optional -25º F (-32º C) cold start package is available .
  • Work up to 9,480 feet (3000 meters) above sea level without de-rating.
  • Track your performance through standard Product Link that provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes and other machine data on demand through VisionLink ® online interface.

Reliable, High and Low, Heat and Cold

        

  • Work up to 3000 m (9,840 ft) above sea level without de-rating.
  •     

  • Standard high-ambient temperature capability is 52º C (125º F) with cold start capability at –32º C (–25º F). 
  •     

  • Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
  •     

  • Three levels of fuel filtration protect the engine from dirty diesel fuel.
  •     

  • Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
  •     

  • The center track guiding guard helps keep the excavator track aligned when traveling and working on slopes.
  •     

  • The sloped track frame prevents mud and debris accumulation, helping reduce risk of track damage.

Work in Comfort in the All-New Cab

        

  • The Comfort cab has a wide seat that adjusts for operators of all sizes. • Control the excavator comfortably with easy-to-reach controls all located in front of you.
  •     

  • Standard automatic climate control keeps you at the right temperature all shift long.
  •     

  • Advanced viscous mounts reduce cab vibration by up to 50 percent over previous excavator models.
  •     

  • Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles. A cup holder, document holder, bottle holder, and coat hook are also provided.
  •     

  • Use the standard radio’s USB ports and Bluetooth® technology to connect to personal devices.

Simple to Operate

        

  • Start the engine with a push button; use a Bluetooth key fob, smartphone app, or the unique Operator ID function.
  •     

  • Program each joystick button, including response and pattern, using Operator ID; it will also remember climate control fan and radio settings.
  •     

  • Navigate quickly on the standard high-resolution 203 mm (8 in) touchscreen monitor or with the aid of the jog dial control.
  •     

  • Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.

Maintenance

        

  • Expect up to 15 percent less maintenance cost than the 320E. (Savings calculated over 12,000 machine hours.)
  •     

  • Do all daily maintenance at ground level.
  •     

  • Check engine oil level quickly and safely with the new ground-level engine oil dipstick; fill and check engine oil on top of the machine with a conveniently located second dipstick.
  •     

  • Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
  •     

  • Do no required maintenance on the Cat Clean Emissions Module.
  •     

  • Change all fuel filters at a synchronized 500 hours.
  •     

  • Expect the new air intake filter with pre-cleaner to last up to 1,000 hours – a 100 percent increase over the previous filter.
  •     

  • The new hydraulic oil filter provides improved filtration performance, anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000-hour replacement interval – 50 percent longer than previous filter designs.
  •     

  • The new high-effi ciency electric cooling fans only run when needed and reverse to keep cores free from debris.
  •     

  • S·O·SSM ports simplify maintenance and allow for quick, easy extraction of samples for fluid analysis.

Safety

        

  • Access 100 percent of daily maintenance points from ground level – no need for you to climb on top of the excavator.
  •     

  • Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the pushbutton starting feature.
  •     

  • The standard ROPS cab meets ISO 12117-2:2008 requirements.
  •     

  • Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab posts and larger windows.
  •     

  • A rearview camera is standard, and a right-side-view camera is optional.
  •     

  • The new right-hand service platform design provides easy, safe, and quick access to upper service platform; the service platform steps use anti-skid punch plate to prevent slipping.
  •     

  • The handrails comply with ISO 2867:2011 requirements.
  •     

  • The lower frame meets ISO 15818:2017 lifting and tie-down requirements.
